I will use code tag !!!

tx

It would start out simple, something like:

awk '{for(i=1; i<=NF; i++) A[tolower($i)]++} END{for(i in A) print i " = "  A}'  file

But then it would get more complicated. If you only use the lowercase form then what do you do with a word like "I" or what do you do with names that start with an uppercase letter, or for instance with "Mr. d'Arcy". You'd want to exclude dots and comma's that cling to words. Is the "-" part of a word or isn't it. Is a number a word, or a combination of a word and a number? Etc. You could make an approximation, for example:

awk -F'[^-_[:alnum:]]*' '{for(i=1; i<=NF; i++) if ($i!="") A[tolower($i)]++} END{for(i in A) print i " = "  A}' file

But to cater for all corner cases is likely going to be a bit complex..
